SMOKING-PIPE no. s673826.

To all whom 'it may concern;

Be it known that I, PATTisoN F. MCCLURE, of Pierre, in the county ofHughes and -State of South Dakota, have invented certain new and usefulImprovements in Smoking-Pipes; and I do hereby declare` the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The objects of this invention are to providein a smoking pipe means.foreffecting the absorption and retention of the nicotin and otherdangerous products of combustion, to enable the draft opening to bereadily freed of obstructions Without in any way interfering with theburning load in the pipe; to insure the burning ofthe entire load; toeffect the cooling of the smoke before leaving the'pipe; to prevent anyContact between the saliva passing down thevstem from the smokers mouthand the load of tobacco in the bowl oi the pipe; and to keep thatportion of the bowl usually grasped by the user relatively cool.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

' In the accompanying drawings, Figure l is a longitudinal section of myimproved pipe. Fig. 2 shows a cleanerinserted while the load is burning.Fig'. 3 is a horizontal section on line 3--3, Fig. l. Fig. 4 shows theabsorbent plug removed. Figs. 5, 6 and 7 show modified forms of plugs.

Referring to the drawings, l. designates the bowl and 2 the stem, theopening of which latter opens into the bowl a short distance above thebottom thereof and on a plane that intersects the opening in the bottomof.`

the bowl. The latter at its bottom has a central opening which is closedby a removable plug 4 which comprises an outer disk 5 and a truncatedcone 6 of suitable absorbent material. This cone, excepting at its base,does not contact with the bore of the bowl, but extends upwardly intothe latter so as to leave an uninter rupted surrounding air spacebetween it and lthe bowl so that the smoke-will be cooled beforeentering the stem, the plane of the opening of which latter isintersected by the cone of the plug. The outer portion of the base ofthe bowl will also be cooled, making it easy to handle. This cone anddisk constituting the plug are preferably made in two pieces, suitablyunited, the disk portion beingcapable of being grasped so that the plugmay be readily turned axially. When the absorbent material becomesheavily charged with nicotin or moisture it may be discarded and freshclean absorbent material substituted.

According to the form shown in Figs. l and 5 the cone is detachablysecured to the disk by a screw 7 extending centrally from the latter,the cone being made entirely of absorbent material its full length. InFig. 6 I have shown a shorter cone detachably secured p Specification ofLetters Patent.

by a screw 7a extending centrally through a base 79 having a disk 7, thebase and disk being of cork or other suitable material. which normallylies below thel bottom of the bowl, need not be of any increaseddiameter, but only of su-iiicient width to act as a stop for the plug,andv at the same time f to permit it to be readily grasped either forwithdrawing the plug or turning the latter in the bowl as -shown in Fig.7. In any event the base of the plug is cylindrical s'o as to fitair-tight against the bore of the bowl, and thus hold the absorbentmaterial centrally within the latter. l

In practice, the tobacco is loaded and packed downA directly on top ofthe plug which will take up all the nicotinY of the tobacco and preventthe same from passing off with the smoke, and likewise saliva` flowingthrough the stem will be absorbed, thus keeping the tobacco perfectlydry. There is no diaphragm or partition of any'kind between the tobaccoload and the absorbent plug. If particles of the tobacco should lodgeover the end of the draft opening they maybe readily dislodged by aslight axial turning of the plug, but should the obstruction be withinthe pipe stem, it may be readily removed by first withdrawing the plugand then blowing through the stem, or by inserting a The lower end ofthe plug, i

straw or cleaning brush therethrough. This may be turbing the load, asshown in Fig. 2.

The advantages of my invention will be. apparent to all smokers. Notonly is the smoke cooled by reason of circling around theabsorbent plug,but the lower exterior of the bowl is kept cool. When a plug becomesthoroughly charged with nicotin or moisture it may be readily withdrawnand a fresh plug substituted, or a fresh cone attached to the disk. Apipe constructed in accordance with my invention is less liable toclogging and readily permits of freeing any stoppage that may occur,this being done while the pipe is in use. lt will also be noted that apipe so constructed permits of great ease in cleaning both the bowl andstem.

I claim as my invention 1. A pipe for smoking tobacco comprising. a bowland a stem, said bowl being open at its upper and lower ends, and saidstem having a draft opening entermgsaid bowl immediately above the loweropen end thereof, and a plug of absorbent material removably fitted inthe lower end of .said bowl and forming the bottom thereof, said pluginY tersecting the plane of said draft opening and forming a support forthe tobacco load above said opening.

2., A pipe for smoking tobacco comprising a-bowl and a stemhsaidbowl'being open vat its upper and lower ends,

and said stem having' a draft opening entering said bowl immediatelyabove the lower open end thereof, and a plug of absorbent materialremovably fitted in the lower end of said bowl and forming the bottomthereof, said plug intersecting the plane of said draft opening andforming 'a support for the tobacco load above such opening', and4 formedto provide a continuous surroundingspace between itself and the wall ofthe bowl.

3. A. pipe for smoking tobacco comprising a bowl and a stem, said bowlbeing open at its upper and lower ends, and said stem havinga draftopening entering said bowl immediately above the lower open end thereof,and a plug of absorbent material removably tted in the lower end of saidbowl and forming the bottom thereof, said plug comprising a truncatedcone of absorbent material intersecting the plane of said draft openingand having a base tted against the lower end of the bowl.

4. A pipe for smoking tobacco comprising' a bowl and a stem, saidbowlrbeing; open at its upper and lower ends, and said stem having adraft opening entering said bowl immediately above the lower open endthereof, and a plug;` of absorbent material removably fitted in thelower end of said bowl and forming the bottom thereof, said plugcomprising a truncated cone of absorbent material intersecting the planeof said draft opening', its lower end pro l jeeting beneath the bowlsutliciently to permit the plugr lo be grasped and forming, a stoptherefor against the botztom of the bowl.

5. A pipe for smoking tobacco comprising a bowl and a stem, said bowlbeing,l open at its upper and lower ends, and said stem having,- a draftopening;- entering said bowl on a plane intersecting the opening in thebottom of the bowl, and a plug of absorbent material removably Titled inthe lower end of the bowl and forming the bottom thereof, said plugforming a support for the tobacco load above said draftopening andbeing; wholly removable without disturbing the load to permit thecleaning of the stein opening;A

ln testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
